DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0020] Please refer to FIGS. 2 to 4. The incombustible fireproof network elevated floorboard of the present invention includes a base seat cover board 2, a central cover board 3, side cover boards 4, leg supports 5 and a connecting seat 6.

[0021] Referring to FIGS. 2 to 4, the base seat cover board 2 is composed of a basin-like base mold 21, a steel reinforcement mesh 211 disposed in the base mold 21 and cement 212 filled up in the base mold 21. The periphery of top face of the base seat cover board 2 is slightly smaller than the periphery of the base mold 21, whereby the top face of the base seat cover board 2 is formed with a peripheral stepped supporting platform 22. In addition, each of four corners of the bottom of the base mold 21 has a projecting supporting seat 23. In addition, the four corners of the base seat cover board 2 are previously formed with through holes 24.

[0022] Referring to FIGS. 5 to 7, the leg support 5 is independently made and is substantially reverse U-shaped seen from lateral side. The top section is formed with a central thread hole 51 corresponding to the through holes 24 of the base seat cover board 2. A hollow plastic cock 241 is disposed in the through hole 24. The inner diameter of the cock 241 is smaller than the outer diameter of a screw 8. When the screw 8 is screwed into the cock 241, a thread is naturally formed. Alternatively, the cock 241 can be previously formed with threaded inner wall. By means of several screws 8, the base seat cover board 2 is fixed with the leg supports 5 in sequence. The connecting seat 6 is a square body. The four corners of the connecting seat 6 are respectively formed with four sockets 61 facing upward. Each socket 61 is disposed with cavities 62, whereby the leg support 5 can be fitted into the cavities 62 of the socket 61. A wire channel seat 7 is defined between the connecting seats 6.
